OK... it's time to give you my results with "Ethos."
While I did get some increase in fuel efficiency, it did not hit the break-even point of a 2 MPG increase. Thought you all would like to know! Here is the screenshot of my Excel spreadsheet and you can see the details for yourself.
Obviously, your results may vary.

Better Gas Mileage?

Just like anybody else, I am looking for ways to save on gasoline costs. Better driving habits help, but until hydrogen fuel cells take over, I'm always on the lookout for promising ideas.
In comes Ethos.
Approaching the additives with much caution and skepticism, this one appears different. Wanting others to benefit if there is something to it, I bit the bullet and decided to make an experiment out of it right here on this traffic blog.
I am now in the process of carefully logging my MPGs for the next few weeks while I wait for the Ethos to arrive. I will bde just as curious as you to see if this does what it claims (up to 19% higher fuel efficiency - click here to see the full documentation).

I hope you will find this experiment interesting. Check back often during the summer as I will share my mileage spreadsheet with you in the coming weeks.
Buy or bust?.... 'dunno! Let's find out....
